HOISTING AND TRAVERSING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 393,643, dated November 27, 1888.

Application lilcd January 6,1888. Serial No. 259,992. (No model.)

To all zzz/"wml t may concern! Be it known that I, NORMAN C. HARRIS, of Poultney, in the county of Rutland and State of Vermont, have invented a new and useful Improvement in Hoisting and Traversing Apparatus, of which the following is a specification.

My invention relates to apparatus which is employed where it is desired to raise a weight, as from a mine-shaft, and then to traverse or move the raised weight laterally for any desired distance to the place where it is to be deposited.

The invention will be hereinafter particularly described, and pointed outin the claims.

In the accompanying drawings, Figure l is a side elevation of an apparatus embodying my invention, showing the carriage as in traversing position. Fig. 2 isasimilar side elevation of a portion of the apparatus, showing the carriage as held in hoisting position. Fig. 3 is an end view of the wheeled carriage and appurtenances, looking toward the right hand of Figs. 1 and 2. Fig. 4 is aside View ofa portion of the roadway and a catch for holding the carriage in position after its traversing movement, and Fig. 5 is a transverse section of the roadway and an end view of a stop which is applied thereto and with which a hook upon the wheeled carriage engages to sponding parts in all the figures.

A designates an elevated roadway, which is formed by a rod or wire cable, and which isA here represented as inclined.

lB designates a carriage, which is provided with wheels B', whereby it is supported upon the roadway A, and which is adapted to be traversed along the roadway A from end to end thereof.

As best shown in Fig. 3, the carriageB consists of two side frames or portions secured together by bolts or stretchers b and straddling the roadway A, and the wheels B',`which are journaled in the side frames of the carriage B, are circumferentially grooved,so as to fit upon the roadway and to run smoothly along the same.

Cdcsiguates a hoisting and traversing cable, which, as here represented, is secured at one end, c, to the wheeled carriage, thence passes over a pulley, C', upon the wheeled carriage, and a pulley, G2, which is in stationary bearings beyond the end of the traversing movement of the carriage,andis then carried downward to a hoisting-drum, G3, upon which it is wound. A bight, 0*, of this hoisting-cable depends from the carriage between the point c and the pulley C', and in this bight of cable is hung a hoisting-pulley, Ot, which is journaled inthe frame O5, to which is attached the hook c or equivalent device, from which the weight to be raised is suspended. The frame C5 has au upwardly-extending stirrup or bail, C6, for a purpose hereinafter described, and which, as the hoisting-pulley is raised, passes into a guiding-funnel, B2, for a purpose hereinafter described.

I have shown the carriageB in Fig. 2 as arranged in hoisting position, and it is obvious that if it be held against lengthwise movement on the roadway A the winding up ofthe hoisting-cable O will lift the hoisting-pulley C4 and elevate the weight desired to be lifted. To hold the carriage B in hoisting position,I have represented a hook, D, thereon, which is pivoted at d, and which is adapted to engage a stirrup or stop, E,upou the roadway. As here represented, the stirrup or stop E is held in position lengthwise of the roadway A by a twopart clamp, E', which may be iiXed in rigid position to said roadway, and upon which I have represented heads or disks e as swiveled at e'. These heads or disks e have the stirrup or stop E rigidly fixed to them, and they are swiveled at e' upon the clamp E', or around the roadway, so that no matter what the position of the clamp upon the cable or other roadiway, A, the disks or heads e' will always turn freely thereon and permit the stop or stirrup E to be returned by gravity to the position shown in the drawings.

If the stirrup or stop E were made a rigid part of the clamp E,the possible twisting cfa cable, if one be used for the elevated roadway, would move the stirrup or stop E in a direction around such cable and would not retain it always in proper position for the engagement of the hook D with it. When, however, the stirrup or stop Eis swiveled at e' upon the clamp E or on the roadway, the stirrup or stop IOO will always gravitate to its lowest position and will be in the proper position for the engagement ofthe hook D. l have also shown in the carriage ll a hook, D', pivoted at d', and which maybe swung into and out of engagement with the stirrup or hanger C, extending upward from the hoisting-pulley frame.

D2 designates a cam,which, as here shown, serves to operate both hooks, D and D. This cam ])`l is fulernmed atdl and is connected with the hooks D and D'. As here represcnted,the cam is connected with the hook D by a pirati, upon the hook entering a curved slot, d, in the cam, and it is connected with the hook D by a pin,d",on the hook entering a curved slot, d", in the cam. In fact, the hooks D D bear against curved surfaces on the cam. rlhc cam D is guided in its turning movements upon the pivot di, and is also limited in its movement by a stop-pin, di, received in a slot, d, which is formed in the cam. The cam slots d d are ofsuch shape, as shown in the drawings, that when the cam is swung from theposition shown in Fig. 2 to the position shown in Fig. l the hook l) will be lowered and the hook D will be swung into operative position across the funnelshaped guide B2, and when the cam is swung down from the position shown in Fig. l to the position shown in Fig. 2 the hooks will be operated in a reverse direction.

l have shown the carriage D as provided with. a fnnnel'shaped guide, 13, at one end, which passes over and receives the stirrup or stop D, and with a corresponding funnelshaped guide, E, at the other end,whieh receives a stop-hook, E2. On the cam Dl are toes or projections d" dm, upon which the sti r rup or stop E and the stirrup or hanger C" opcrate as they enter their funnel-shaped guides Bix B2.

The roadway A, as here represented, is inclined downward toward the position to which the carriage must go to be in hoisting position, and which is over the mine shaft or other place from which weight is to be hoisted. \Vhile the hoisting-pulley C4 has no weight suspended from it, and when the hoisting-cable C is paid out, the hook D is engaged with the stirrnp or hanger C and prevents the hoistingpulley C from being lowered by such paying ont thereof, and as fast as the cable C is unwound from the drum C the wheeled carriage B will travel along the roadway A toward the left of the drawings and until it comes to the position shown in Fig. 2. Vhile it is thus moving toward the left, the hook D is depressed out of operative position,as shown in Fig. l, and the toe d upon the cam D'z is protruded across the funnel-shaped guide B3. .As the carriage moves downward the funnelshaped guide passes onto the stirrup or stop E, and by such stirrup or stop acting upon the camtoe d" the cam is swung from the pos sition shown in Fig. l to that shown in Fig. 2. By this movement of the cam DL the hook D is raised into engagement with the stirrup or stop E, as shown in Fig. 2, and the hook D is swung laterally ont of engagement with the stirrup or hanger tj, and thereafter, as the hoisting-cable U is paid ont, the hoisting-pulley C will be lowered into position for the desired weight to be attached to it.

As the cable C is wound up upon the drum C the hoisting-pulley C is raised, the cam DL' being meanwhile in the position shown in Fig. 2, and as the stirrup or hanger enters the funnel-shaped guide ll it acts upon the eanrtoe d and turns the cam to the position shown in Fig. l. This movement of the cam swings the hook D into engagement with the stirrup or hanger C" and lowers the hook D out of engagement with the stirrup or stop E, and as the draft upon the hoistingcahleCeontinues the carriage ll will be moved laterally along the roadway A until the draft upon the cable C ceases.

'lhe hooked stop lll2 is placed on the roadway at the end of the traversing movement of the carriage, and as the rarriage is moved along the funnelshaped guide l' passes over the hook W, and said hook is raised by and engages with a stirrup, l-l, formed upon the end ofa rod, l,whioh is connected at ci with the cam D. As the funnel-shaped guide il* passes over the hook E the sti rrup liis inthe position shown in Fig. l; but as the winding up ofthe cable C ceases weight comes upon the hook Ff and it pulls the stirrup lil forward to the position shown in Fig. 2,and thereby turns the cam D to the position shown in Fig. 2, thus swinging the hook D ont ofengagement with the stirrup or hanger `(3 and i permitting the hoisting-pulley and weight to be lowered, while the carriage is held against downward movement along the roadway by the hooked stop El. After the weight is deposited the winding-cable again drawn up, and the sti rrup C,cntcring the funnel-shaped guide 13"', acts upon the cam Di and swings thc hook D into engagement with the stirrup or hanger C, thereby returning the cam DL to the position shown in Fig. l.. The hook E and stirrnp E constitute a retaining device for the carriage.

ln Fig. l ll have shown the hooked stop E as pivoted at c" and as supported by disks or rotary heads o, swiveled upon the ends of a clamp, E', as shown in Fig. l, and by means of a downwardly-extending cord, c, the hook E may be lifted ont of engagement with thestirrup E3 when it is desired to release the carriage D and permit it to move downward to a hoisting position. The operator who controls the winding drum C should of course be signaled when the f u nnclshaped guide D* reaches the hooked stop 15; but in case heis not thus signaled or does not properly respond to such signal the stirrup E would soon reach the shoulder c upon the hook E2, or the funnelshaped guide would strike against the parts supporting said hook and cause breakage. To prevent this the hook E'z may, if desired, be pivoted at c in a slide, c, mounted on the roadway A, as shown in Fig. 1, and may be connected by a cord, el, with the heads or disks CIJ ICO

IIO

c, which constitutethe support for holding the hook with the carriage engaged with it. This rope or flexible connection e7 permits the slide c to be moved back readily for a considerable distance in case the carriage B cornes in contact with it. If, however, the person controlling the hoisting-drum Ciis properly signaled and properly responds to his signals, the arrangement shown in Fig. 4 is all that is necessary and maybe relied on without the employment of the slide c and the cord or fiexible connection c7.

As best shown in Fig. 8, there are in opposite sides of the funnel-like guide B3 inclined iianges b,which bear upon the stirrup or stop E as the said guide passes onto the stirrup or stop, and thus hold said stirrup down for the hook D to properly engage with it.

From the above description it will be understood that the operation of the apparatus in changing from hoisting to traversing and from traversing to lowering at the mouth of a mineshaft or other place where the hoisting is solely performed is automat-ic. As the wheeled carriage B is returning to the hoisting position the cam D2 is operated to unlock the stirrup or hanger CG from the carriage and to lock the carriage to the stirrup orstop E,and the further paying out of the cable C lowers the hoistingpulley G4. As the hoisting is completed the stirrup or hanger C6 enters the funnel-shaped guide B2 and operates the cam D2 to unlock the hook D from the stirrup or stop E and to lock the hook D upon the stirrup or hanger CG.

From the above description it will be understood that the cable C constitutes both a hoisting and a traversing cable, and that the hooks D E2, with the stirrups E E3, consitute locks,whereby the carriage Bis held at opposite ends of its traversing movement. The hook-D also constitutcsa lock for holding the hoisting-pulley C* suspended independently of the cable C.

As shown, the pins d cl'rgwhereby the hooks D D are connected with the cam D, are nearly or quit-e in lines drawn between the pivot d2 of the cam and the shoulders of the hooks, and henceapressure against the hooks transversely to their length has no tendency to turn the cam and disengage the hooks.
